perf tools: Fix perf regs mask generation
commit f47822078dece7189cad0a5f472f148e5e916736 upstream.
On some architectures (powerpc in particular), the number of registers
exceeds what can be represented in an integer bitmask. Ensure we
generate the proper bitmask on such platforms.
Fixes: 71ad0f5e4 ("perf tools: Support for DWARF CFI unwinding on post processing")
